> URL parsing doesn't support multiple fragment identifiers
I'm surprised that RFC 3986 (like 2396) makes '#' reserved in
fragment identifiers (only '[]', too). The fragment ID is terminated
only by the end of the URI after all. The one reason for disallowing
'#' I can think of is tokenization starting from the end of the
string, but as far as I know that may fail for other parts.
fragment = *( pchar / "/" / "?" )
pchar = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded = "%" HEXDIG HEXDIG
sub-delims = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" /
"," / ";" / "="
<http://www.example.com/site.jar#/path/inside/foo.html%23heading1>
should work fine, though.
-----8<--------8<--------8<--------8<--------8<--------8<--------8<-----
I'm also surprised that RFC 3986 (unlike 2396) misses a section on US-
ASCII characters deliberately excluded, i.e. <C0> and '"<>{}|\`^ ',
previously also '[]'. I think
reserved = gen-delims / sub-delims
gen-delims = ":" / "/" / "?" / "#" / "[" / "]" / "@"
...
should be something like
reserved = delims / enclosing / unwise / controls
delims = gen-delims / sub-delims
enclosing = DQUOTE / "<" / ">" / SP
unwise = "{" / "}" / "|" / "\" / "`" / "^"
controls = %x00-1F / %x7F
...
